NSX Disconnecting from vCenter

[sandhog]

Randomly NSX is disconnecting from vCenter. Once this happens, NSX doesn't show registration with vCenter (no green light). The following error was noted:

NSX Management Service operation failed.( I/O error on GET request for "http://localhost:7441/api/2.0/services/vcconfig": Read timed out; nested exception is java.net.SocketTimeoutException: Read timed out )

- KB states to upgrade to 6.1.5. Current version is 6.2.2.

- Check DNS and no record was created to resolved NSX. Record created and resolution - both ways - verified. Monitored the status for a few hours.

- Checking the logs today. I might have seen some "untp...." error entries. Will get back with any findings.

- Any comments?

Thank you!

Is DWF enabled? Might be useful to run packet capture from NSX Manager to VCenter Server for a certain number of hours depending on when issue occurs. Using the pktcap-uw tool in ESXi 5.5 and later (2051814). Does issue persist if vcenter and NSX Manager is on the same host?

hi there sir,

I have a similar issue in the past but seem slithy different, so in my case I went to nsx manager, go to enable mode and do a show log manager follow, from there check what exactly ERROR message is painted and post it here.
